To all whom it may concern:

Be it known that I, JOSEPH H. GLAUBER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Im rovements in lGaskets, and do declare the ollowing is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in gaskets, and theinvention consists in a gasket body of flexible material provided with a metallic seat or seating portion at one end, the same constituting a new article of manufacture and sale, all substantially as shown and described and particularly polnted out in the claims.

In the accompanying drawings Figure l is a perspective v1ew ofthe gasket complete, and Fig. 2 is a sectional view of one half of the same lengthwise. Fig. 3 is a sectional elevation of a gasket and one form of the fittings with which the gasket is adapted to be used, and Fig. 4 is a sectional elevation of the gasket and modified form of fitting.

The gasket as thus shown comprises two separate parts or portions A and B, which are mechanically united and constitute a single article for sale and use. As such the body A is elastic or flexible and of substantially thimble shape, and the metallic seat or seating portion B is fixed in the front or forward end thereof. The said portion or body A is preferably made of rubber, while the said seating portion is preferably of brass though it may be of any comparatively so'ft metal or composition of metals. These two ortions or elements are mechanically united by mounting the seatB in body'A by a suitable 'interlocking connection, whereby the said seat is permanently but removably fixed in said body. Furthermore, the said seat or seating portion and said body have the same internal bore or cross section, and said seat is preferably threaded inside but not necessarily, and is also preferably rounded or tapered at its front, where it rejects in advance of body A, as herein s own, and the said body is shown as conforming to the ta-l per of the front of said scat. This construction enables the complete article to be used in ipe connections where a fiuid tight joint is esired and the meeting parts are adapted to theuse of such a gasket. If the said metallic seat and the part on which it is seated be properly fitted to each other the joint so made will be rendered fluid tight when the arts are locked together with the usual couping nut, and this enables nie to employ this article with liquids which have a deterioratin effect on rubber or like gaskets, the meta lic. seat B taking the lace of exposure and protecting the rubber lliody A.4

In Figs. 3 and 4, D represents a portion of a pipe which is threaded externally at its end and adapted to have the said gasket screwed thereon, and E is an end of opposite pipe lof larger cross-section with a more or less rounded seat 5 corresponding to the tapered end of the gasket and threaded externally and adapted to be engaged by coupling nut C. F represents a washer inter osed between the said gasket and the immediate end of pipe E ieid against which the gasket is adapted to In Fig. 4 the construction is so far modified that pi e G corresponding to pipe D in Fig. 3, has a xed plane 6 and a smooth exterior over which the gasket is sleeved and bears against said flange. In either case as the coupling nut is tightened the gasket is com-A pressed, and being elastic expands more or ess in the threads of the' pipes wherever the threads are exposed. The initial seating and' sealing is against the metallic ortion of the gasket and the ultimate and e ective sealing is the yielding portion thereof.

hat I claim 1s:-

1. As a new article of'manufacture, a gasket consisting of a yielding' body and a metallic seating portion removably fixed therein and projecting in advance of said body at its center and its outer surface 'conforming to the curvature of said body, and said parts having a uniform internal bore adapted to make a tight seat on a ipe fitting.

2.' As a new article of manufacture, a gasket comprising a compressible body gradually tapered at its seating end and a metallic seating portion fixed centrally in the front of said body and extending forward therefrom to seat in advance thereof, said seating portion having both its outer and its inner surfaces Hush with thev corresponding lsurfaces tion of said rbber body and the bore of the of said body and constituting an essential vsaid Vparts substantially the same. 10l
